I created this website to help all R learners to undestand how to plot beautiful/useful charts using the most popular vizualization package
ggplot2.
It won't teach you how to write a code, but definitely will show you how ggplot2 geoms look like, and how manipulating their arguments changes visualization. Few scrolls below you can find list of covered geoms and example of what they plot.

If you have any questions, suggestions, inquiries, ideas how to improve the app or superinteresting data project, you can mail me pawel [at] databall.co.
And thank you to all good people who helped me to build this app
Piotr,Patrick,Donal
and
